"During the coding period, I will first work on the boot loader. I intend to modify the existing x86 boot loader so that it is capable of loading both a 32-bit Haiku kernel and a 64-bit one. Once this is done, I will work on implementing the x86_64 architecture functionality in the kernel. Finally, I will port modules and drivers to the 64-bit kernel. Should I have time, I will also begin work on porting userland." Heck. Yes.

menuetos is 64-bit but has that made any difference to it's popularity?
Speaking of which, I just had a look at menuetos website ... it's got USB2 support and DVB-T support in assembly now? Far out. Sorry, get back on topic. Good luck to Alex - nothing wrong with that project.
